The purpose of this study is to assess students' attitude and satisfaction of university foodservices. We conducted a survey for this study using questionnaires with 400 university students. A total of 344 students answered with a usable response rate of 86.0%. We performed a statistical data analysis using SPSS program for $X^{2}-test$ and t-test. Students visited university foodservices more frequently for lunch than for breakfast or dinner. Students' food choice depended on taste of food. The main reasons for using university cafeteria included 'a low price' and 'economy of time'. The prior complaint factor on university foodservices was 'taste of food'. Students were more satisfied with a price than other factors. They marked 'a variety of menu' as the least satisfied. The matters, such as 'more delicious food' and 'more various menu' were pointed out for improvement. In conclusion, developing tastier food and diversifying a menu are required to enhance the quality of university foodservices.

The purpose of this study was to investigate the effects of oriental medicinal plant extracts added to chocolates on the moisture content, color, radical scavenging activity and sensory characteristics. The oriental medicinal plant extracts were added at a weight percentage of 0, 4 and 8%. As the ratio of the extracts in the chocolates increased, the moisture content, color, and radical scavenging activity increased. In sensory evaluation, significant differences (p<0.05) were shown in taste, bitterness, and overall acceptability depending on the addition of oriental medicinal plant extracts but there were no significant differences in chocolate aroma and texture.

To study the importance of family meals in adolescents, 251 middle school students were surveyed through a questionnaire on their family meal patterns, dietary behaviors, food intake, and life satisfaction. The family meals were defined as "meals with all family members living together" by 62.2% of the students. For the frequency of family meals, 42.2% of the students replied having family meals "More than once a day". A common reason for the difficulty in having a family meal was a "lack of time" (73.3% of the students). Students tended to respond that they would be most fond in having meals with entire family members with traditional Korean food. Having more frequent family meals was found to benefit both individual and familial dietary behavior. In terms of food intake according to the frequency of family meals, the group having frequent family meals consumed significantly more rice, tofu, legumes, meats, fishes, eggs, green vegetables, seaweeds, fruits, milk, and milk products. This indicates that students can achieve a balanced diet through family meals. In terms of emotional status, the group having more frequent family meals showed a higher satisfaction with their daily life, health, nutritional status, and care from their relatives. In terms of personal mental status, the group having more frequent family meals was also found to be more effective at controlling undesirable emotions such as loneliness, indignation, and lethargy. As a result of this study, students in the group having more frequent family meals were found to have a positive dietary behavior, a balanced nutrition, a higher life satisfaction, and a more stable mental status. This result is useful as nutritional and educational information in schools to impress upon the public the importance of family meals for adolescents.

Purpose: People have long been interested about antioxidant nutrients such as vitamin A and E to stay in healthy states. This present study provides trustworthy nutritional information and evaluates vitamin A and E contents in emphasized food items. Methods: Vitamin A or vitamin E emphasized foods including beverage, cereal, snack, chocolate product, other cocoa products, and sugar products were analyzed. The contents of vitamin A, E in samples were examined by high performance liquid chromatography. Vitamin A and vitamin E contents were compared with the labeled value indicated on the nutrition label. Results: Vitamin A (n=18) value ranged from 90% to 248% and vitamin E (n=20) value ranged between 96-413% of labeled value. Analyzed samples ranged more than 80% of the labeled value, which complied with food labeling rules. Conclusion: Providing accurate information for nutrition label is essential to confirm nutrient contents in foods. It will help to decide the adequate level of nutrient intake. Therefore, the nutrition labeling system should be supervised continuously with regular monitoring analysis.

The purpose of this study was to compare dietary behavior and food intake in relation to physical complaints, such as farmer' syndrome(FS) and gastro-intestinal(GI) problem among Korean farmers. The questionnaire was composed of 24 Cornell Medical Index (CMI), 8 farmers' syndrome, and 5 GI problem questions. Food intake data was gathered by the semi-quantitative food frequency method. The subjects(male 226, female 415) who had FS and Gi problem were 12./8% and 8.3%, respectively. The physical complaints were higher in female and the elderly group. In the FS group, lower activity was seen that in normal groups. The lower health status and fatigues were found in the physical complaint groups. Dietary behavior showed low appetite in the physical complaint group, irregular lunch in FS, and irregular breakfast in GI problem group. Changes in dietary behavior were shown in the aspects of lower amount of intake quantity(40.8%), lower consumption in fat(32.8%) and salty(38.8%) foods, and diverse food items(47.8%). Quantity of food consumed was significantly different withing groups with FS. Kinds of food consumed, intake of protein source foods, milk and calcium and total animal foods were lower in the FS group. But milk and calcium source food and all animal food intakes were higher in the GID problem group. The results suggest that dietary behavior and food intake differ within the group of physical complaints.

BACKGROUND/OBJECTIVES: Atherosclerosis is associated with increased inflammation in the visceral adipose tissue (VAT). Vitamin D has been reported to modulate the inflammatory responses of stromal vascular cells (SVCs) and adipocytes in adipose tissue, but the role of vitamin D in atherosclerosis biology is unclear. This study examined the effects of in vitro 1,25-dihydroxyvitamin D₃ (1,25[OH]₂D₃) treatment on the inflammatory responses of SVCs and adipocytes from atherosclerotic mice. MATERIALS/METHODS: C57BL/6J (B6) mice were divided randomly into 2 groups and fed a 10% kcal fat control diet (control group, CON) or 41% kcal fat, 0.21% cholesterol (high fat + cholesterol, HFC) diet (obese group, OB), and B6.129S7-Ldlr^tm1Her/J (Ldlr^-/-) mice were fed a HFC diet (obese with atherosclerosis group, OBA) for 16 weeks. SVCs and adipocytes isolated from VAT were pre-incubated with 1,25(OH)₂D₃ for 24 h and stimulated with lipopolysaccarides for the next 24 h. Proinflammatory cytokine production by adipocytes and SVCs, the immune cell population in SVCs, and the expression of the genes involved in the inflammatory signaling pathway in SVCs were determined. RESULTS: The numbers of total macrophages and SVCs per mouse were higher in OB and OBA groups than the CON group. The in vitro 1,25(OH)₂D₃ treatment significantly reduced macrophages/SVCs (%) in the OBA group. Consistent with this change, the production of interleukin-6 and monocyte chemoattractant protein 1 (MCP-1) by SVCs from the OBA group was decreased by 1,25(OH)₂D₃ treatment. The 1,25(OH)₂D₃ treatment significantly reduced the toll-like receptor 4 and dual-specificity protein phosphatase 1 (also known as mitogen-activated protein kinase phosphatase 1) mRNA levels in SVCs and MCP-1 production by adipocytes from all 3 groups. CONCLUSIONS: These findings suggest that vitamin D can attribute to the inhibition of the inflammatory response in VAT from atherosclerotic mice by reducing proinflammatory cytokine production.

The purpose of this study is to examine the food consumption behavior, the attitudes to food sanitation and the HACCP(?) knowledge of college students. Questionnaires were collected from 130 students in Daejeon University. The subjects mainly purchased their food at big discount stores and thought of expiration date as a most important factor considered. When purchasing the grocery, female students seldom took the convenience cooking into consideration, however, 10.3% of male students concerned it(p<0.05). In subjects' knowledge of food hygiene, the average score was 16.21 and in their performance(p<0.05)of it, the average score was 11.14. Especially in their knowledge of separate food storage, the average point was 5.03 and in their performance of it(p<0.05), the average point was 2.84. 72% of respondents had ever experienced food sanitation education. Of students who answered that food sanitation education was very helpful, the number of students living in university dormitory or boarding houses was as much again as that of students living in their own places. 82.2% of students did not know about HACCP system. They wanted to know 'the meaning(43%)', 'the necessity' (19.6%), 'the advantage(9.3%)' of HACCP and 'the kinds of food products adopting HACCP(28%)'.

The current socioeconomic climate has meant more children spend more time alone at home even for dining. This study was performed to characterize modem Korean childrens´food ecology based on mealtime atmosphere. A total of 705 elementary school students, 347 girls and 358 boys took part in the study. They were chosen evenly from the Seoul metropolitan areas, provincial cities, or rural areas, and were asked to fill out a questionnaire. The questionnaire was categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The average height, weight, body mass index, and Rohrer index were 143.2cm, 37.6kg, 18.2 and 127.2 respectively. A significant number of children(39.2%) answered their bed time was between 11 and 12 pm. Only 28.3% answered that the whole family has breakfast together, and 47.7% have dinner together. A considerable number of children, 17.8% for breakfast and 6.9% for dinner, answered they eat alone. Most of the children answered they like to have dinner with the whole family. Half of the children answered they do not feel hungry before having breakfast. Proportions of children for their favorite meal time were 66.8%, and 25.4% and 7.8% for dinner, school lunch, and breakfast respectively. The largest proportions of children, 53.3% and 68.7%, have breakfast and dinner at home. Most of the children(75.2%) never purchase their dinner. Forty two% of the children answered they like school lunch, however, 60% of children answered they leave portions of lunch uneaten occasionally or always. Only 38.0% and 46.2% of the children have nutritionally adequate diet for breakfast and dinner. Children having more meals with the whole family possessed a more positive attitude towards breakfast compared to the children who eat with the whole family less frequently. In conclusion, Korea children are exposed to different health threatening food ecology problems related to changing environments, and consistent concern and support from community nutritionists are required.

This study investigated the effects of chitosan on mineral metabolism in rats exposed to cadmium by oral administration. Six week-old Sprague-Dawley rats were divided into eight groups. Four groups were fed AIN-93G based 3% ${\alpha}$-cellulose diets and the other four groups were fed 3% chitosan diets for four weeks with the oral administration of 0, 0.5, 1.0, 2.0 mg Cd/2ml distilled water three times per week, respectively. The essential mineral contents of serum, liver, kidney and bone (femur and lumbar), and the excretion of calcium in feces and urine were determined. There was no significant difference in weight gain and food intake among groups. The cadmium administration significantly decreased calcium in serum, iron in blood, calcium and iron in liver and iron contents in kidney. In contrast, calcium and zinc contents in kidney increased by the administration of cadmium. The weight, length and breaking forces of the femur and lumbar were not significantly different due to cadmium administration and chitosan among the groups. The fecal excretion of calcium was increased by the administration of cadmium. On the other hand, calcium absorption and the absorption rate were decreased by Cd administration. In the groups without Cd administered (N, N-Chi groups), chitosan significantly decreased the absorption rate of calcium by increasing the excretion in feces (p<0.05). These results suggest that cadmium administration may facilitate the decline of essential minerals in rats and also, chitosan may have a conflicting effect between cadmium and the essential minerals of tissues.
